Estonia
Georgia (now Republic of Georgia)
Kazakhstan
Kirgiziya (now Kyrgyzstan)
Latvia
Lithuania
Moldavia (now Moldova)
Russia
Tajikistan
Turkmenistan,
Ukraine
Uzbekistan

and

(2) 20 autonomous soviet socialist republics: 16 within Russia, 2 within Georgia, 1 within Azerbaijan, and 1 within Uzbekistan

Answer 2

Moldova, Ukraine, Kazakhstan, Uzbekistan, Tajikistan, Turkmenistan, Lithuania, Latvia, Estonia, Georgia, Azerbaidjan, Armenia, Kyrgyzstan, Byelorussia, Russia, Karelo-Finland

Answer 3

Moldova, Ukraine, Belarus, Lithuania, Latvia, Estonia, Georgia, Azerbaidjan, Armenia, Kazakhstan, Uzbekistan, Tajikistan, Turkmenistan, Kyrgyzstan, Russian Federation.
these are 15 and were the soviet republics that formed the USSR.
the two more u are thinking about could be autonomous regions inside some of these republics. for example Chechnya in the Russian Federation. or maybe self-declared independent republics such as Transnistria in Moldova. i'm writing down only these two because they are the most involved in a struggle for independence and the most likely to rise the number to 17.

Answer 4

Established by four Soviet Socialist Republics, the USSR grew and from 1956-91 politically contained 15 republics — Armenian SSR, Azerbaijan SSR, Byelorussian SSR, Estonian SSR, Georgian SSR, Kazakh SSR, Kyrgyz SSR, Latvian SSR, Lithuanian SSR, Moldavian SSR, Russian SFSR, Tajik SSR, Turkmen SSR, Ukrainian SSR, and Uzbek SSR — joined in a strongly centralized federal union. After the USSR's collapse, all 15 SSRs became independent countries. Thus, the question was suppose to be 15 rather than 17 unless if you counted Poland and Czechoslovakia but that was merely part of the satellite countries that constituted the Warsaw Pact.
